BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention relates to the fabrication of bamboo products and more particularly, to the fabrication of modularized bamboo frame member set for making bamboo baskets, racks, shelves and the like.

(b) Description of the Prior Art

Various materials including ceramics, glass, wood, plastics, stainless steel, and etc. may be used for making tables, chairs, cabinets, storage containers, and many other furniture. To show an antique sense of beauty, wood and bamboo are intensively used to make furniture and storage containers. A conventional bamboo furniture is known comprising a frame structure and a plurality of wall panels formed of bamboo strips by weaving. These bamboo panels have open spaces, and are fastened to the frame structure by an adhesive or by means of binding wires There is known another structure of bamboo furniture in which the bamboo panels are formed of transverse bamboo slats and longitudinal bamboo slats, and the transverse and longitudinal bamboo slats are fastened together by rattan cords. The fabrication of this structure of bamboo furniture requires much time and labor, and therefore the cost of this structure of bamboo furniture is high.

There is also known another design of bamboo storage container that is invented by the present inventor, comprising a top frame, a bottom frame, and a plurality of bamboo slats connected between the top frame and the bottom frame. The bamboo slats have the respectively top and bottom ends respectively fastened to respective bottom mounting holes on the top frame and respective top mounting holes on the bottom frame. Because the bamboo slats are springy, it requires much time and labor to fasten the bamboo slats to the top frame and the bottom frame. Further, the top frame and the bottom frame are each formed of four bamboo slats, and the four bamboo slats are connected to one another end to end to form a rectangular open frame. The fabrication of this design of bamboo storage container also requires much time and labor. Therefore, this design of bamboo storage container is not suitable for mass production. Further, the top frame and the bottom frame have sharp angles, causing less sense of beauty.

To eliminate the drawbacks of the aforesaid bamboo storage container design, the inventor of the present invention created a modularized bamboo frame member set and filed to the USPTO under application Ser. No. 11/863,299. According to this design, bamboo poles are cut into straight bamboo strip elements and then the bamboo strip elements are processed into are processed into curved bamboo rod members through a compression molding press so that the curved bamboo rod members are selectively used and connected end-to-end to construct rectangular, circular and oval bamboo frame members for making bamboo baskets. FIG. 12 shows one example of this design of modularized bamboo frame member set in which two bamboo strip elements respectively processed into a respective

-shaped bamboo rod member so that the two

-shaped bamboo rod members can be connected end-to-end to construct a rectangular bamboo frame member. FIG. 13 shows another example of this design of modularized bamboo frame member set in which four bamboo strip elements of two different lengths are respectively processed into a respective L-shaped bamboo rod member so that the four L-shaped bamboo rod members can be connected one another to construct a rectangular bamboo frame member. FIG. 14 shows still another example of this design of modularized bamboo frame member set in which three bamboo strip elements of two different lengths are respectively processed into one

-shaped bamboo rod member and two L-shaped bamboo rod members so that the bamboo rod members can be connected one another to construct a rectangular bamboo frame member.

According to the aforesaid modularized bamboo frame member set, every constructed bamboo frame member has a planar configuration. Bamboo baskets, racks, shelves or the like constructed of these bamboo frame members show less variation in design.
